Several areas of ixgbe were written before widespread usage of the BIT(n) macro. With the impending release of GCC 6 and its associated new warnings, some usages such as (1 << 31) have been noted within the ixgbe driver source. Fix these wholesale and prevent future issues by simply using BIT macro instead of hand coded bit shifts. Also fix a few shifts that are shifting values into place by using the 'u' prefix to indicate unsigned. It doesn't strictly matter in these cases because we're not shifting by too large a value, but these are all unsigned values and should be indicated as such. Signed-off-by:

This brings the logic closer to how we handle the stats in ixgbe and it sets us up for introducing per-queue stats. Use IXGBEVF_STAT and IXGBEVF_NETDEV_STAT for accessing the driver and netdev stats respectively. This way we don't have to calculate the stats based on register values which could lead to the counters not being initialized properly when the interface is down. IXGBEVF_QUEUE_STATS_LEN is set to include the number of queues. Also some defines were renamed to use the IXGBEVF prefix. Signed-off-by:

This field is used to record the RX queue index for a redirect action passed via ring_cookie field in struct ethtool_rx_flow_spec which is a u64 value. For ex: after adding a filter rule to redirect to a VF using ethtool # echo 4 > /sys/class/net/p4p1/device/sriov_numvfs # ethtool -N p4p1 flow-type ip4 src-ip 192.168.0.1 action 0x100000000 querying for the rule shows the Action as 'Direct to queue 0' # ethtool -n p4p1 4 RX rings available Total 1 rules Filter: 2045 Rule Type: Raw IPv4 Src IP addr: 192.168.0.1 mask: 0.0.0.0 Dest IP addr: 0.0.0.0 mask: 255.255.255.255 TOS: 0x0 mask: 0xff Protocol: 0 mask: 0xff L4 bytes: 0x0 mask: 0xffffffff VLAN EtherType: 0x0 mask: 0xffff VLAN: 0x0 mask: 0xffff User-defined: 0x0 mask: 0xffffffffffffffff Action: Direct to queue 0 With this fix, ethtool will report the right queue index even for VFs. Action: Direct to queue 4294967296 Here 4294967296 corresponds to 0x100000000. We need to update 'ethtool' to report the queue index as a Hex value so that it is more user friendly and matches with the 'action' value that is passed when adding the rule. Signed-off-by:

X550EM_a/x did not have a default value for mac->ops.setup_link which was causing link issues for backplane devices. This patch sets mac->ops.setup_link to ixgbe_setup_mac_link_X540 for X550EM_a/x which is also default for X550. This will result in mac->ops.setup_link calling the link setup function for the respective PHY type in case we do not need a special function to deal with it. Reported-by:

Previously the PF driver would only set VLAN spoof checking if the VF had created VLANs. This was done by setting and checking a counter (vlan_count) whenever a VLAN was created by the VF. However it is possible for the vlan_count to be !=0 while there are no VLANs assigned to the VF due to the count incrementing every time a VLAN 0 is added on ifdown/up, which resulted in VLAN spoofing always being set for those VFs. This patch cleans up the logic by unconditionally setting VLAN based on how the VF is configured (via ip link set ethX vf Y spoofchk on/off). This change also resolves an issue where the VLAN spoofing can remain set even after being disabled by the user due to the driver enabling VLAN spoof checking every time a VLAN is added to the VF, but would only allow changes in the setting if vlan_count != 0. Also default_vf_vlan_id and vlans_enabled were removed from the vf_data_storage structure since they are not being used in the driver. Signed-off-by:

Consolidate the logic behind configuring spoof checking: Move the setting of the MAC, VLAN and Ethertype spoof checking into ixgbe_ndo_set_vf_spoofchk(). Change ixgbe_set_mac_anti_spoofing() to set MAC spoofing per VF similar to the VLAN and Ethertype functions - this allows us to call the helper functions in ixgbe_ndo_set_vf_spoofchk() for all spoof check types and only disable MAC spoof checking when creating MACVLAN.

Linux TCP stack painfully segments all TSO/GSO packets before retransmits. This was fine back in the days when TSO/GSO were emerging, with their bugs, but we believe the dark age is over. Keeping big packets in write queues, but also in stack traversal has a lot of benefits. - Less memory overhead, because write queues have less skbs - Less cpu overhead at ACK processing. - Better SACK processing, as lot of studies mentioned how awful linux was at this ;) - Less cpu overhead to send the rtx packets (IP stack traversal, netfilter traversal, drivers...) - Better latencies in presence of losses. - Smaller spikes in fq like packet schedulers, as retransmits are not constrained by TCP Small Queues. 1 % packet losses are common today, and at 100Gbit speeds, this translates to ~80,000 losses per second. Losses are often correlated, and we see many retransmit events leading to 1-MSS train of packets, at the time hosts are already under stress. Signed-off-by:

Pablo Neira Ayuso says: ==================== Netfilter updates for net-next The following patchset contains Netfilter updates for your net-next tree, mostly from Florian Westphal to sort out the lack of sufficient validation in x_tables and connlabel preparation patches to add nf_tables support. They are: 1) Ensure we don't go over the ruleset blob boundaries in mark_source_chains(). 2) Validate that target jumps land on an existing xt_entry. This extra sanitization comes with a performance penalty when loading the ruleset. 3) Introduce xt_check_entry_offsets() and use it from {arp,ip,ip6}tables. 4) Get rid of the smallish check_entry() functions in {arp,ip,ip6}tables. 5) Make sure the minimal possible target size in x_tables. 6) Similar to #3, add xt_compat_check_entry_offsets() for compat code. 7) Check that standard target size is valid. 8) More sanitization to ensure that the target_offset field is correct. 9) Add xt_check_entry_match() to validate that matches are well-formed. 10-12) Three patch to reduce the number of parameters in translate_compat_table() for {arp,ip,ip6}tables by using a container structure. 13) No need to return value from xt_compat_match_from_user(), so make it void. 14) Consolidate translate_table() so it can be used by compat code too. 15) Remove obsolete check for compat code, so we keep consistent with what was already removed in the native layout code (back in 2007). 16) Get rid of target jump validation from mark_source_chains(), obsoleted by #2. 17) Introduce xt_copy_counters_from_user() to consolidate counter copying, and use it from {arp,ip,ip6}tables. 18,22) Get rid of unnecessary explicit inlining in ctnetlink for dump functions. 19) Move nf_connlabel_match() to xt_connlabel. 20) Skip event notification if connlabel did not change. 21) Update of nf_connlabels_get() to make the upcoming nft connlabel support easier. 23) Remove spinlock to read protocol state field in conntrack. ==================== Signed-off-by:

Hannes Frederic Sowa says: ==================== net: network drivers should not depend on geneve/vxlan This patchset removes the dependency of network drivers on vxlan or geneve, so those don't get autoloaded when the nic driver is loaded. Also audited the code such that vxlan_get_rx_port and geneve_get_rx_port are not called without rtnl lock. ==================== Signed-off-by:

Equivalent to "vxlan: break dependency with netdev drivers", don't autoload geneve module in case the driver is loaded. Instead make the coupling weaker by using netdevice notifiers as proxy. Cc: Jesse Gross <jesse@kernel.org> Signed-off-by:

Currently all drivers depend and autoload the vxlan module because how vxlan_get_rx_port is linked into them. Remove this dependency: By using a new event type in the netdevice notifier call chain we proxy the request from the drivers to flush and resetup the vxlan ports not directly via function call but by the already existing netdevice notifier call chain. I added a separate new event type, NETDEV_OFFLOAD_PUSH_VXLAN, to do so. We don't need to save those ids, as the event type field is an unsigned long and using specialized event types for this purpose seemed to be a more elegant way. This also comes in beneficial if in future we want to add offloading knobs for vxlan. Cc: Jesse Gross <jesse@kernel.org> Signed-off-by:
